LAMP ATTACHMENT.

Specification of Letters Patent.

Patented Aug. 28, 191?.

Application filed. February 24, 1917. Serial N 0. 150,769.

To all whom it may concern Be it known that I, GEORGE SAMUEL HUNT, a citizen of the United States, residing at Beaverdam, in the county of Hanover and State of Virginia, have invented new and useful Improvements in Lamp Attachments, of which the following is a specification.

The present invention relates to improvements in lamp burners, and is primarily such burners, and the improvement resides in the novel construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

A simple and satisfactory embodiment of the improvement is illustrated by the accompanying drawing, in which:

Figure 1 is a side elevation, partly in section, of a lamp burner constructed in accordance with the present invention, parts being broken away and parts being in section, the dotted lines indicating the holding means for the chimney when the latter is swung away from the burner as when igniting the wick of the burner,

Fig. 2 is an elevation looking toward the filling tube connected with the burner,

Fig. 3 is a detail transverse sectional view illustrating the flame extinguishing device for the wick tube,

Fig. 4 is a plan view of the blank from which the spring chimney-engaging mem bers are formed,

Fig. 5 is a detail enlarged sectional view approximately on the line 5-5 of Fig. 1,

Fig. 6 is a similar sectional view approximately on the line 66 of Fig. 1.

Fig. 7 is a detail elevation looking toward 4 the hinged portion of the U-shaped chimney receiving ring, and

Fig. 8 is a similar view looking toward the opposite side of the ring.

The burner is broadly indicated by the 45 numeral 1, the same being provided with the usual base or gallery 2 from which centrally extends the dome 3 that incloses the wick tube 4. The burner is provided with the usual threaded depending sleeve 5 which engages with the threaded opening in the bowl of the lamp (not shown). Surrounding the wick tube 4 is a cuff 6 that has its lower end preferably flared outwardly or otherwise weighted, the weighted portion. .55 of the said cufi contacting with the inner arm 7 of the operating lever 8, The lever adapted as a chimney holding device for tions which I have 8 may have end 7 bifurcated, so as to straddle the wlck tube 4: and to engage with the opposite lower edges of the cuff 6. The

base 2 of the burner may be slitted or othersaid eye, movement of the said lever in an opposite longitudinal direction being limited by the bifurcated. end 7 thereof engaging with one of the edges of the wick tube 1.

The burner as illustrated by the drawings is provided with a filler member 11 in the nature of a tube, the outer end of the said tube being extended angularly in an upward direction, providing the mouth 12 '1 for the said filler member and this mouth, normally, is closed by a flanged cap 13. Secured to the opposite sides of the filler member are spring plates 14-14t, the said plates being inturned to provide lugs 15, the said lugs being disposed to overlie the cap 13 to retain the said cap in position upon the mouth of the filler spout. It is, of course, to be understood that the tubular filler spout communicates with the bowl of the lamp through the tubular threaded portion 5 of the burner, the wick tube 4 extending entirely through the said threaded portion as illustrated in Fig. 3 of the drawing. The spring arms 14, beyond the inturned portermed the lugs 15 are rounded outwardly away from each other, as indicated by the numerals 16, and these portions 16 are adapted to exert a tension toward each other and the purpose of such arrangement will be presently described.

Upon the base 2 of the burner l, and surrounding the dome thereof is arranged a cross sectionally U-shaped ring member which is indicated by the character 17.

The lower portion of the chimney 18 is adapted to be received in this ring member, and if desired to be contacted by the sides of the said ring, the bottom edge of the chimney resting upon the lower wall of the ring, as illustrated in Fig. 1 of the drawin s. This ring 17, as clearly illustrated in Figs. 5 and 7 of the drawings, has its side walls slotted longitudinally, the said slots terminating away from each other and the metal provided between the slots is bent outwardly forming arms 19 upon the outer flange and similar arms 20 upon the inner flange. Likewise, and as illustrated in Figs. 6 and 8, the side walls of the U-shaped ring member, diametrically opposite the referred to slots, are provided with additional slots, and the metal between the said slots is bent outwardly providing arms 21 upon the inner flange and arms 22 upon the outer flange. By reference to the said Figs. 5, 6, 7 and 8 of the drawing, it will be noted that the outer slots are of a greater length than the inner slots and conseqnently the arms 19 and 22 are of a greater length than the arms 20 and 21 and the purpose of this arrangement will also be presently apparent. It is, of course, one of the principal objects of the present invention to provide means whereby the lamp chimney 18 will be effectively retained upon the burner, and in addition to the engagement of the said chimney with the cross sectionally U-shaped ring member 17, I provide spring arms which are adapted to engage with both the outer and inner faces of the chimney, as illustrated in Figs. 1 and '2 of the drawing. These arms are each constructed from a single blank of material similar to that illustated in Fig. 4 of the drawing comprising a longitudinal bar 23 and has its ends formed with lateral ex tensions 2d and 25 respectively. The bar 23, at a suitable distance from the lateral extension 25 and at a greater distance away from the lateral extension 24f has its edges widened, at spaced intervals, and notched, as at 262 6 and 27-27. The bar, between the spaced notches 26 and 27, is bent upon itself to, underlie the ring 17, and the arms 19 and 22 upon the ring, are bent to engage in the notches .26, while likewise the respective arms 20 and 21 are bent to engage in the notches 2727 of the respective chimney engaging members. The members are shaped to conform to the cross sectional contour of the chimney 18, the lateral extensions 24c and 25 being rounded in plan so that the members 25 will contact with the outer face of the chimney and the arms 24: will likewise engage with the inner surface of the chimney, as clearly illustrated in Figs. 1 and 2 of the drawing. The shorter arms 20. and 21 of the ring member when bent around the spring chimney-engaging elements will contact with each other, as illustrated in Fig. 5 of the draw ings, while the longer arms 19 only partially engage with the outer face of one of the outer spring arms that are extended in parallel spaced relation to receive therebetween a lug 28 which is secured to the base 2, the said arms being pivotally secured to the said lug, as indicated by the character 29. The second pair of longer arms 22 are bent around the outer face of the second onter spring chimney-engaging arm or member in a position to engage with. the said stop r whereby to lock the ring upon the base of the burner. By reference to Figs. 1 and 2 of the drawing it will be noted that the arcuate spring members 16 are disposed diametrically opposite the pivotal connection of the ring member to the burner, so that the said members 16 will receive the chimney 18' when the catch 33 is brought from engagement with the lng-31,and the bnrner swung to a position to be received by the said members 16. This permits of the flame being extinguished and the wick being trimmed or a new wick being applied to the wick tube, but by the provision of the cuff member 6 and the operating lever8 th e or, t w l beaPPa -n ha a d w ward pressure upon the said leverwill bring the same to the position to elevate the cuff above the top of the wick tube and consequently smother the flame from the wick.

From the above description, taken connection with the accompanyingdrawing, the simplicity of the device, aswell as the advantages thereof will, it is though, be per- 7 to the burner, spring chimney engaging members each bent around the ring and extending therefrom and said ring bein g slitted to the opposite sides of the said chimney engaging members and the material between the slits being bent around the said members, whereby to connect the members to the ring.

In a chimney holding lamp burner, a U-shaped ring upon the base thereof and adapted to receive the bottom of the chimney, a' lug uponthe base of the hurner, a spring catch disposed diametrically opposite the lug, said ring having its side members slittedin opposite directions from diainetrica lly opposite points thereon, spring chimney engaging members each bent around the ring to provide inner and enter arms, said arms having their ends formed with lateral extensions, said arms, at the portions there'- of disposed opposite the sides of the ring being notched, themetal between the refered to slits in the ring being bent to engage within the said notches to hold the spring arms to the ring, the said outturned metal upon the outer side of the ring engaging the opposite sides of the referred to lug and being pivotally secured thereto, the metal upon the outer side of the ring diametrically opposite the lug being extended to provide an element adapted to be engaged by the spring catch.

3. In combination with a lamp burner having a movable cufl surrounding the wick tube thereof, and being provided with a filler spout having a flanged closure, of a chimney holding means for the said burner, including a Ushaped ring which is arranged upon the base of the burner and which is adapted to receive the lower edge of the chimney, a pivotal connection between the ring and the burner, spring catch means for retaining the burner upon the base, spring chimney engaging members each comprising an element bent around the ring and secured to the sides of the ring for engaging with the inner and outer surfaces of the burner, spring members secured to the filler tube to the opposite sides thereof and having in turned portions which engage with the cap of the tube to retain the same seated, said spring members being extended in an outwardly curved direction from the portions thereof engaging with the cap, whereby to provide a rest for the chimney when the ring is disengaged by the catch and swung upon its pivot outwardly of the burner.

In testimony whereof I aflix my signature.

GEORGE SAMUEL HUNT.
